I try to extend the core/quote block of Gutenberg by a inline SVG (quote symbol) to the html and adding a color panel so the color can be changed.
Any hint how to do this?

Reset to default 0Do you receive any errors in the browser dev tools while you have the block editor open?
One improvement that I immediately notice is that your call to the block editor should be:
const {
InspectorControls,
getColorObjectByColorValue,
} = wp.block-editor;
not block.editor.
